So, i have had dayz mod for a while now. It was always stuffing up so i eventually gave up on it. Recently i have decided to try and play, so i deleted all the files for arma 2/oa and dayz mod on steam. I attempted to join my friends server through steam, running the up to date version of dayz through commander. As usual i get the message 'error: Addon dayz:amin requires CA_Dubbing_Counterattack' and proceeded. I then get told i'm missing some sound files and continue.i see a flash of the lobby and my game exits, followed by 'Cannot load world ca\chernarus\chernarus.wrp'. Help!
